Polygala amadei (Polygalaceae) is described from Nebrodi Mountains in Sicily. Related to P. preslii, the other Sicilian endemic of the genus, it differs from it both for its morphological characters and for its different phenology and ecology. Its population, although localized, occurs in a vast mountain territory, located in the north-eastern sector of the island of Sicily, rich in woods and large clearings, which have been grazed by cattle, sheep and horses for centuries. Confused in the past with the endemic P. preslii, the new species is sufficiently distinct and is also related to subspecies of P. alpestris from the south of the Italian Peninsula. In addition to the diagnostic characters and a brief analysis of the relationships with some similar taxa occurring in southern Italy, the ecological and chorological characters of the new taxon are reported, then comparing them with P. preslii, with which the Nebrodi species still remains highly related.

The results of the first 30 years of editorial activity of the International Foundation pro Herbario Mediterraneo through the publication and distribution of the journals Flora Mediterranea and Bocconea are reviewed. They consist of 683 articles and scientific notes on Flora Mediterranea, 664 articles plus 12 monographs on Bocconea. In particular, 125 new species, 22 subspecies, 4 varieties and 9 nothospecies of vascular plants are reported, mainly from Sicily, Greece, Spain, Turkey, peninsular Italy and Algeria. Furthermore, the indices of the 30 issues of both periodicals and the lists of all the new taxa and nothotaxa published in them are reported: among these a genus of Fungi. The lists of the numerous taxonomic and nomenclatural variations proposed are also presented. Although marginal, a few new syntaxa described are listed. In the review, special attention was given to the karyologycal data published in Flora Mediterranea since the first issue. It concerns 1194 taxa related to the native vascular flora of many Mediterranean countries. Among the most investigated floras, those of Bulgaria, Greece, Turkey, Spain and the Italian Peninsula stand out. The review also examines the data of the first contributions of a second column devoted to plant germination started with volume no. 29 (2019) of Flora Mediterranea. Specific quantitative data by themes, taxonomic groups and geographical areas are reported for the two journals respectively
